It is more important to fix the leaks when converting to the drop in refrigerants. Like 410a, they leak their blend at different rates and will loose their efectiveness. Just converted my wife's parents unit to mo99 due to the cost difference. Fixed the leaks and changed out the dryers and shrader cores. At that time r22 cost over $500 a jug while I could get the mo99 for about $150 per jug.
